From Stuttgart with a diecast and some photos

[Sgt.Pinback]

Hello,

my name is Uli, I am 53years young and have had HONDAS from 1978 onwards when I made my licence. I stated with a CB 400, came to CB 500 (witth 600ccm engine) to two CB 750 KO in 1981. As a student I restored those two 1969 KO´s (without money and without internet), sold one of them and traded the other one 1984 to a CBX 1000. I drove the CBX for aroung 75 tkm together with a Z1-R until 2003.


Here is an old pick from 1981




I recently purchased a 1970 CB 750 because all the years the KO was anchored in my mind.

Its a One -owner from new, unrestotred but very well looked after machine. The owner just passed away at around 80. Sadly, I could not seek to him, but he must have been a realy CB 750 enthusiast. The machine was still registrated. I got the complete historie.

With the bike I had to purchase a mass of old CB 750 spare parts. Most of them I have to sell to get the space.. and some mones back.

So here are some pictures.

Please have a look and feal free to do some "critisism" because I whant to bring her back to genuine specs (I assume over the years a lot had been changed to keep her running).

As far as I can see the fuel tank is K2 (the genuine wrinkle tank in ruby red is here bt has a dent) and the pipes are 341 not 300.

First pick in the her new garage. I dismanteled that rack (already in ebay..) and changed those chrome - pipe - guards and cleaned her



After a few hours of cleaning





Of course there is "patina".






I made a lot of picks today , please feel free asking me for details to see what should be changed, what is not KO correkt, what would you do....

Thank you for watching,

Uli

Hi Uli,

Check mal meinen Youtube Kanal Ferenz1111, und bei Interesse gib Laut.
Das sind meine Bikes auf dem Kalender, den ich seit Jahren für die Four Szene mache.

Fourfache Grüße und Four fourever,

Hallo Uli,
I believe it was much more difficult to restore these bikes in the age without internet. On the other hand, tehre were lot of parts for good price....
You are talking about the fuel tank. The wrinkle tank is on the bike ? Because the tank on the bike can´t be from K2 I think, because there was not red K2, or I have not seen it. Not correct are rear shocks and front fender, also the seat was redone not correctly. Your VIN number will help us. But it looks like the chain guard is original with rear 45T sprocket, and it is good. Your VIN number will help us. I guess 14000-20000 ?
By the way I have two questions. 1st: Is it Z1-900 in your garage ? 2nd: Did you pay full price for this bike, or did you get any discount form price that was in the add ?

Hi John,

the tank actually on the bike is not the tank it originaly came with. I think it is K1 or K2 (see the chrom guard with black stripe). The original wrinkle tank is here in the box:






It has a big ding so the owner changed it (I assume) to the actual tank. Luckily, he kept it!

I will have fixed it and with the set of sidecovers, lamp and ears and  airbox (that came with the bike) I will have it re-painted in ruby red.

Are you sure with the rear shocks? I thought they have the correct KO- spring ?




Here is a detail from the seat



I hope it is still the original seat.

I think, the cushion (?) is just flat, maybe due to age, maybe because the owner made it flat.

I will bring it to a saddler, telling he may rescue as much of the old cushion as possible, upholster it and fix a new cover.

John,

I will not talk about money a paid for it. But I think the price was fair enough. And with all the spareparts it is OK for both sides.
Was this bike resp. the offer discussed here?


And good eye John,

that´s  my 1973 Z1

[Sgt.Pinback]

VIN is 18.9xx,

(Engine some numbers +)

[CBman]

That´s great you have both best bikes of 70´ ! Very nice Z1. You have my admire. Sorry talking about the price. If there were any spare parts, it was very fair price. I don´t think it was seen here.
Rear shocks are definately not correct for K0. Yours are from K2 and newer CB750. K0 should have thinner middle body, because there is black plastic cusion on the bottom. Your seat is also definately not correct. Maybe the cover was from KO, but the seat pan and the seat lock are from 71 and newer CB. Also the foam on K0 should be red and yellow for your VIN. The tank will be from K1. Maybe someome else will find more not correct parts. But I hope for you there will be no other.
So this is list:
- front fender   -your VIN should has single cut
- shocks
- seat

[Sgt.Pinback]

Thanks for the compliment.

And for the info, of course!

I add another photo from the seat. Just to be sure.

When the whole seat is wrong (or is it only the lock?), I will look for a new one and wont have that one restored.

Do you or somebody else have a pic of the correct KO diecast seat/ lock?

[hondasan]

I believe the seat IS the original seat base, but someone has attached a k2 style seat lock assembly - you can therefore restore it back to correct when you find thw original type seat catch.

Thank you Chris for the info. I also think it is the original seat, with a  downholstered cushion, shortened lace and a newer lock/catch.

I will go through the boxes and have a look if I find the original ones.

Anyhow, the ignition key fits in the catch  actually.

If I am not lucky, what do I need to by?

Thanks for input

Hello Uli,
yes, from the last picture it is clear now. The seat pan (base) is original K0. We can see two threads for original seat catch below new one. So somebody should drilled new two holes for K2 seat catch. Maybe someone wanted to have a lockable seat that was more safe.
Anyway the foam is not original.
Yes, both ebay links are correct. Just the first link is not complete seat catch. So use the hook 77235-300-010 + complete seat catch 77230-300-000. And you are missing one rubber : 77204-292-000.

[Sgt.Pinback]

Thank you. Good eye with the rubber, didn´t see that yet.

BTW, I realize that my side cover badges look into the wrong direction..... and even so on my old blue KO 30 years ago above!

Or is this Special German Layout ?  


The wrinkle tank will be sent to the painter next week. How can I dismantle the tank badges?

Hi Uli,

schönes Gespräch von vorhin, anbei meine mail Adresse: ferenz.tom@t-online.de

Fourzüglich Grüße,
Tom.

[Sgt.Pinback]

Yes, thank you for the call. Lots of priceless info from you.

Here are two photos from that other mirrors. Look slightly different to those actual on the bike.






Regarding my seat I do now do not know what to do: buying a new from yamiya (but that will hav ethe 2Wrong" foarm) or restoring mine with correct red foarm and cover.....

[Ferenz62]

Hi Uli,

die mail Adresse ist ferenz.tom@t-online.de

Fourfache Grüße,
Tom.

[hondasan]

If it was mine, I would restore the seat that you already have, with a red foam and cover from Yamiya. Cheaper and more correct - from memory Yamiya's new seats have a seat base which strictly is only correct for the first thousand or so sandcasts (the base has a different arrangement of holes as compared to your base). Yamiya's are great seats, but you do appear to have the correct seat base to start with.
Just my view - Chris R.
